Report of activity of the volcano Turrialba:
October 28, 2016, update 17 hours

Since yesterday, the passive emission of ash from the volcano Turrialba continued, with some brief rest beaches and several energetic pulses. The eruption was accompanied by tremors of magnitude low to moderate with some brief rest intervals. On average, the amplitude of tremor has increased slightly in the afternoon. The few observations made possible by visual webcam suggest that eruptive columns do not exceed 1000m above the crater. IMN weather stations indicate that the wind was variable today, generally between the West and the Northeast.

The OVSICORI-A will issue a report every day at 17 hours on the activity of the Turrialba volcano.

October 28 11:00 h (October 28, 16:00 GMT)

In the last 24 hours the seismic records of the surveillance system at Popocatépetl Volcano recorded 237 low-intensity exhalations with emissions of steam, gas and sometimes small amounts of ash. Also three explosions were recorded yesterday at 16:20 and 16:41 h , and today at 05:04 h .
On the other hand, along the time covered by this report were recorded 65 minutes of very low amplitude harmonic tremor.



At night incandescence was observed over the crater .
At the time of this report we see the volcano with continuous emission of steam and gas in a westerly direction .
CENAPRED emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments .

This type of activity is included within the scenarios Volcanic Traffic Light Yellow Phase 2.

Cleveland , Alaska :

52°49’20 » N 169°56’42 » W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

An explosion at Cleveland Volcano was detected in both infrasound (air pressure) and seismic data at 13:10 AKDT (21:10 UTC) Monday, October 24, 2016. The explosion was heard by residents of Nikolski 45 miles (75 km) east of the volcano. No ash fall was reported in Nikolski or other communities east of the volcano, and no ash clouds were detected in satellite data.


Clear, post-explosion web camera views of the volcano showed a darkened area around the summit crater which may have been the result of minor ash fallout. Narrow dark streaks also were observed extending down the upper snow-covered part of the edifice which may have been produced by small flows of meltwater and ash. Clear satellite views of the volcano this week showed no thermal signals at the summit.

Short-lived explosions at Cleveland Volcano are common and are typically detected by AVO instrumentation on the volcano. The volcano remains in a restless state and AVO continues to monitor the volcano closely.
